update v14.2

small changes to keep it up to date with the latest version

I just checked and this branch still passes all the tests on the latest Elixir. The build is failing because .travis.yml has an outdated Erlang version. If you wanted to update this PR to have:

otp_release:
  - 17.1

Maybe @mururu would be able to merge then? Would be great to have this working on current Elixir.

what do you mean with to update pull request to have otp_release -17.1?
Do you mean to somehow specify erlang version?
Since now Elixir is v15 it is not latest now

Sorry if I was unclear. The Travis CI tests are erroring because Travis is configured to install Erlang R16B, which is incompatible with the latest Elixir. You don't need to specify an Erlang version for the app, it's just for the CI tests.

If you update the .travis.yml file as I mentioned above this build will pass, and hopefully @mururu can merge your branch.

I've tested your branch on Elixir 15.0 and it works fine, so no need to worry about that.
